Demodulation for other inmarsat signals #11

Closed shinetots closed 8 years ago

shinetots commented 8 years ago

Hi. I found jaero amazing! I've just tested jaero with these sample signals found at http://www.sigidwiki.com/wiki/Inmarsat_Aero . I would like to ask if jaero can also demodulate/decode other inmarsat signals like Inmarsat-B and C. Thanks!

I’m glad you like JAERO. Inmarsat-B and C use different modulation techniques so JAERO can’t demodulate them, they also have different coding so JAERO also can’t decode them either. Inmarsat-C uses BPSK (easy to demodulate) Inmarsat-C uses some sort of multi frequency thing.

I see. Is jaero exclusive only for aero signals? Are there any other inmarsat signals that can be demodulated through jaero? How about adding another demodulator class in the source code?

Yup JAERO is just for Aero data. JAERO still can't decode any Aero audio Aero signals though.

Rather than adding another demodulator class and decoder class I would write another program for non aero signals; that would make more sense. I would like to make an Inmarsat-C demodulator and decoder one days but I currently don't have much free time for the next 6 months at least.
